GG 257 peach colord, oval pill?

My mom told me its xanax and she knows my tolorance for xanax (or any pill/ medacine) is extremely high so she gave me 2 and a half wich she told me is like half of a yellow 2mg stick and those sticks barely hit me (usualy takes an hour or 2 to feel anything) if i took the 2 and a half will my body be alright for it? i usualy dont take xanax but when i do i take an entire yellow stick or white stick and its always for sleeping. i have severe insomnia and anxiety and at night its the worse. just need to sleep :p
